What a Notice of Readiness Actually Is
A Notice of Readiness (NOR) is a formal written notice given by the vessel's master to the charterer, shipper, or receiver, stating that the vessel has arrived at the agreed location and is ready in all respects to load or discharge cargo. It is a short document — often a single page — but its correct tendering is what actually starts the laytime clock running under most charter parties, making it one of the most commercially consequential documents in a port call, as covered in our broader guide to [laytime, demurrage, and the ship agent's documentation role](/blog/laytime-demurrage-explained-ship-agent-documentation-role-2026).
The Three Conditions for a Valid NOR
For a NOR to be considered validly tendered, three conditions generally need to be met, and charter party disputes very often turn on exactly one of these three points. First, the vessel must have arrived — meaning it has reached the location specified in the charter party, which itself can be a genuinely contested question (a berth charter party typically requires actually reaching the berth, while a port charter party may only require reaching a location within the port's legal or commercial limits).
Second, the vessel must be ready in all respects — holds or tanks cleaned and prepared, cargo gear operational, all necessary certificates and documentation in order. Tendering NOR before the vessel is genuinely ready, hoping to start the clock early, is a well-known risk that can render the notice invalid if challenged.
Third, the notice must be tendered in the manner and form the charter party specifies — often requiring written notice during specified office hours, sometimes with a required acknowledgment or countersignature from the receiving party.
Why the Timing of Tendering Matters So Much
Most charter parties include a "turn time" provision — a set number of hours (commonly six) after NOR is tendered before laytime actually begins counting, giving the receiving party reasonable time to prepare. This means the exact tendered time genuinely matters down to the hour, not just the day, since it directly shifts when the turn time expires and laytime formally starts.
At anchorage specifically — common at congested ports where a vessel must wait for a berth — many charter parties include a "Whether in Berth or Not" (WIBON) or "Whether in Port or Not" (WIPON) clause specifically to allow NOR tendering (and laytime commencement) even before the vessel physically reaches the berth. Whether such a clause applies, and how it interacts with the specific charter party wording, is exactly the kind of detail an agent tendering NOR needs to get right.
The Agent's Practical Role
The ship agent typically handles the actual mechanics of tendering NOR on the master's behalf — preparing the document, delivering it to the correct receiving party through the correct channel, and obtaining and retaining acknowledgment of receipt, ideally with a timestamp. This is not a purely administrative task: an agent who tenders NOR promptly the moment the vessel is genuinely ready, through the correct channel, with proper acknowledgment retained, is directly protecting the operator's laytime position.
Conversely, a delay in tendering — even a few hours, waiting for a more "convenient" moment rather than tendering the instant the vessel is ready — can shift the entire laytime calculation in the charterer's favor, a real, quantifiable cost traceable directly to agency performance rather than any genuine operational necessity.
What a Well-Handled NOR Actually Looks Like
A properly handled NOR includes: the exact date and time of tendering, clear confirmation the vessel has arrived at the location specified in the charter party, an explicit statement of readiness in all respects, and — critically — documented acknowledgment of receipt from the charterer, shipper, or their agent, ideally countersigned with a received time noted. If acknowledgment is refused or delayed, a competent agent notes this clearly and continues to protect the owner's position through the vessel's own documented tender, since disputed acknowledgment is itself a common source of later disagreement.
Conclusion
The Notice of Readiness is a short document that carries outsized commercial weight, since its correct, prompt tendering is what actually starts the laytime clock under most charter parties. An agent's competence in getting the timing, readiness confirmation, and acknowledgment right — covered in more depth in our guide to [pre-arrival information ship agents need](/blog/vessel-pre-arrival-information-checklist-ship-agents-2026) — is a genuine, measurable factor in an operator's laytime and demurrage exposure, not a minor administrative detail.
Frequently Asked Questions
Q: What happens if NOR is tendered before the vessel is actually ready?
A: It risks being challenged as invalid, which can delay when laytime is deemed to have started — the vessel would typically need to re-tender once genuinely ready, potentially losing the time between the invalid and valid tender.
Q: What does WIBON mean in a charter party?
A: "Whether in Berth or Not" — a clause allowing NOR to be tendered, and laytime to begin, even before the vessel physically reaches its berth, commonly used at congested ports where anchorage waiting time would otherwise unfairly extend the charterer's effective laytime exposure.
Q: Does NOR need to be in writing?
A: Most charter parties require written notice, though the specific form and delivery method (in person, by email, via the agent) should follow exactly what the charter party specifies, since deviating from the specified method can itself be grounds to challenge validity.
Q: How can operators evaluate whether their agent handles NOR tendering competently?
A: A maritime services directory such as [PortServiceFinder](/ports) lets operators review verified agent profiles by port, and it's entirely reasonable to ask directly about an agent's NOR tendering process and documentation practices before appointment, particularly for chartered voyages where laytime outcomes carry real financial weight.
